PotentialEnergyKineticEnergyTimeDifferencesbetweenWe present here a model that explains in a simple, easy and summarized manner, the values, meaning and reasons for the force of gravity, using simple physical tools. According to this model, a gravitational field actually creates different energy levels...
Conservation of Mechanical Energy:Consider a rafflesia flower that has been released from a pole and it falls towards the surface. In this illustration, the rafflesia flower loses its gravitational potential and gains kinetic energy. The sum of these ...
This equation implies that (given by (2.3)) is a Killing vector if and only if the Ricci tensor is invariant under the complex structure, meaning that . Furthermore, the ASD Weyl tensor must be Petrov type-D: decomposing in terms of its principal spinors as (where is the spinor conjugat...
Hydrostatic balance is the first manifestation of the gravitational potential energy in fluid systems. It reflects the fact that the pressure at any point in a static fluid is determined by the weight of the fluid above it. In this chapter we give a general thermodynamic derivation of hydrostatic...
meaning there’s the greatest potential for actually finding a counterpart. As the sensitivity of the detectors improves, its only going to get more difficult to find a counterpart to a typical gravitational-wave signal, as sources will be further away and less well localized. However, having mo...
difficult one. We attempt to discuss gravitation from another angle in this work. Based on experimental analysis and theoretical verification, a hypothesis regarding mass in gravitational fields is presented. It can avoid the problem of singularity, and the meaning of gravitation is simple to ...
Finally, we demonstrate that DeepGraviLens is able to detect the presence of gravitational lenses, and specifically gravitationally-lensed supernovae, in real Dark Energy Survey (DES) data [28]. The obtained improvements in the classification of lensing phenomena will enable a faster and more accur...
Gravitational wave telescope place extremely high demands on structural thermal deformation, making material selection a critical issue. Carbon fiber reinforced polymer (CFRP) is an ideal choice for the support structure of telescope due to its low coeff
[138], so that formally none of the PTAs have been able to claim a statistically significant detection of GWs in the nHz band, meaning that the measured correlations can merely be seen as evidence for GWs in the PTA data. Hopes are that the addition of more recent data and the ...
